It is?
Lets see:
-50C:
M 1 0w40: 71373.7
SSO 0w30: 69002.4
ASL 5w30: 80868.5
-45C:
M 1 0w40: 36800.0
SSO 0w30: 33793.2
ASL 5w30: 39279.5
-40C:
M 1 0w40: 19994.2
SSO 0w30: 17569.0
ASL 5w30: 20265.4
-35C:
M 1 0w40: 11388.7
SSO 0w30: 9637.3
ASL 5w30: 11037.2
Oh look, there we go, at -35 is where we are close to parity. Any temperature below that, M1 0w40 is thinner.
I also put TDT 5w40 in there and at -35, it is 32292.6..... I'm scared now! LOL! I may do an M1 0w40 oil change..... I'm almost at 10,000Km anyways.
